The geospatial summary of the High Peaks/Summits of the Juneau Icefield is a compilation of the basic geospatial properties (location, elevation and prominence) of the peaks/summits within the general area of the Juneau Icefield located North and East of Juneau, Alaska extending north to Skagway, Alaska. The peaks are classified by elevation: 2000 m, 2050 m, 2100 m, 2150 m, 2200 m, 2250 m, 2300 m and above 2400 m. Most (216, 79%) of the 272 summits compiled have not been assigned an official name[1] by the United States Geological Survey (USGS) Geographic Names Information System (GNIS) and as such are delineated as "Un-Named" (UNP in the KML file).

In addition, select minor peaks are included to report those that are contained within the GNIS database and to permit assigning a location marker (coordinate) for Nunatak identification and ridge delineation for the USGS Hydrologic Unit Code boundaries for cross referencing these areal shapes to a single coordinate.

The elevation of the peaks and summits of the Juneau Icefield was determined by referencing multiple sources including:

The GNIS database consistently reports the peak elevation lower than the referenced USGS and/or USFS topographic maps. The topographic maps also report lower elevations than selected GPS measurements conducted by personnel of the Juneau Icefield Research Program, but not to the degree of the GNIS database.

In this article, the topographic map values were used to report elevation above mean sea level (MSL), unless a more accurate GPS measurement was available.

          Summit topographic prominence

          Summarize
          Perspective

          The Mountaineering definition of a peak in the United States has an informal threshold of 2,000 ft (610 m) of prominence that signifies that a peak has major stature, therefore some peaks reported in this article may not satisfy the requirements for determining a First Ascent. The Clean Prominence,[3] Optimistic Prominence[4] and Isolation[5] should be verified for a First Ascent attempt. The following table contains all peaks/summits within the boundaries of the Juneau Icefield whose prominence has been determined. The values for Key Col elevation, Isolation distance, Isolation Location and peak prominence were obtained from Peakbagger.com

                  International Boundary Line peaks and monuments

                  Perspective

                  These peaks and monuments (survey markers) were designated as part of the Alaska Boundary Settlement of 1903 and associated later surveys. Elephant Promontory is not an official Boundary Peak even though it lies on the International Boundary Line. It was added to assist in delineating the boundary. The peaks in the table below are those that are adjacent to the Juneau Icefield.

                  The Coordinates provided above were taken from the most current satellite photographs(Google Earth Pro) and as such represent the most accurate representation of the location of the boundary peak. Topographic maps of this area are dated (see USGS Historical Topographic maps) and do not provide the accuracy of the Global Positioning System that recent Satellite photographs have. Boundary Peaks 87–91 and 112–117 are not actually summits, but monuments (survey markers) placed by the U.S. National Geodetic Survey.

                  1. USGS Topographic maps show Monument 114 as a monument at [CT 365] with an elevation of 6,788ft, while Google Maps shows it as Boundary Peak 114 with the name of White Pass at [CT 366] with an elevation of 2,107 m. The actual Peak called White Pass is located north of the Google Map coordinates.
